Well, honey, any shape that looks the same after a 180-degree spin is what we call a shape with 180 degrees rotational symmetry. So, we're talking about shapes like squares, rectangles, and even circles. Basically, if it looks just as good upside down, you've got yourself a shape with 180 degrees rotational symmetry.

A trapezoid does not have rotational symmetry. Rotational symmetry occurs when a shape can be rotated by a certain angle and still appear the same. In a trapezoid, the angles and side lengths are not equal, so rotating it will result in a different shape. Therefore, a trapezoid does not have rotational symmetry.
If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
Yes, a cane does have rotational symmetry. A cane can be rotated 180 degrees and still appear the same, making it a symmetrical object. This is because a cane has a cylindrical shape with uniform features around its axis, allowing for rotational symmetry.
how many lines of symmetry has an equilateral triangle
A rhombus is a quadrilateral that has no line of symmetry but has rotation symmetry. Rotation symmetry means that the shape can be rotated by a certain degree and still look the same. In the case of a rhombus, it has rotational symmetry of order 2, meaning it can be rotated by 180 degrees and still appear unchanged.
